Hi
Can't update OTA.from 2.3.23 to 2.3.30 (Menu > Settings > About Phone > System updates)
When i choose Update now, phone reboots but doesn't update the system. It's still 2.3.23
Ok, looks like I solved the problem.
Deleted APN, wiped cache and data all over again, turn on phone, checked MMS settings if everything is ok, filled up missing info, .. and now works. Funny, strange, weird.
It just shows "sending" and nothing happens. After xy minutes I get message unable to send MMS.
I've checked APN settings everything is as it should be, none of the problems with my carrier (where I work as technician btw heh ..).
Phone doesn't lift up data session to MMSC.
by the way, internet...
This will be fixed in next update
